LIGHTING-FIXTURE.

Specification of Letters Patent.

Application filed September 13, 1915. Serial No. 50,496.

To all whom it may concern:

Be-it known that I, HARRY G. ADAM, a

' citizen of the United States, residing at St.

Louis, Missouri, have invented a certain new and useful Improvement inLighting-Fixtures, of which the following is a full, clear, and exactdescription, such as will' enable others skilled in the art to which it.appentains to make and use the same.

This invention relates to indirect and semi-indirect lighting fixturesof the type in which a diffusing shield or bowl isarranged under thelighting unit some distance from the underside of the top reflector ofthe fixture. In the fixtures of this general type that are now in usethe diffusing shield or bowl is suspended from the top reflector bymeans of chains or links and the top reflector is connected to theceiling or to a sup porting structure in various ways.

The main ob ect of my present lnvention I is to provide an inexpensivelighting fixture of the general type mentioned that presents a neat andornamental appearance and to this end I have devised a fixture in whichboth the top reflector andthe diffusing shield or bowl are carried by aplurality of rods, bars or pieces of heavy wire that are connected to asupporting element, preferably a shell that is arranged above the topreflector and which forms a housing for the electric lamp socket thatsupports the lightingunit, said shell being arranged adjacent theceiling of the room or mounted on a pipe, chain or piece of tuning thatdepends from the ceiling.

Another object is to provide an inexpensive lighting fixture of thegeneral type mentioned, which is so constructed that the top reflectorand the diffusing shield or bowl can be adjusted easily to adapt thefixture-to electric lamp bulbs of different sizes without destroying theproper 1'elatidil.-between the filament of the bulb and the topreflector and bowl.

Other objects-and desirable features of my inv ntion will be hereinafterpointed out.

Figure 1 of the drawings is a side elevational view, partly in verticalsection, of a lighting fixture constructed in accordance with myinvention. Fig. ,2 is a similar view of a fixture constructed inaccordance with o portion 2 of the device. The devices 2are preferablyso designed that the loweredge of the shell E will be arranged a shortdis.-

my invention, which is adapted to be mounted on a pipe or tube thatdepends from the ceiling of a room. Fig. 3 is a bottom plan view qf theshell that incases the lamp socket Patented J uly 4, 1916.

and which acts as a support for the devices that carry the top reflectorand the diffusing shield or bZ-iivl'; and Fig. 4 is" a detail sectionalview, illustrating a slight modification of my invention. f

Referring to the drawings, which illus trate the preferred formof myinvention, A

designates the top reflector of the fixture, which may be formed eitherof metal or of translucent material, the underside of said topre'fiectorbing enameled or coated with a brilliantv reflecting surfaceif said member is'formed of metal. 1'

B designates the diffusing shield or bowl that is arranged under thelighting unit C, which preferably consistsof a single electric 'lampbulb, said bowl B being formed either of translucent material or ofopaque material, depending upon whether the fixture is a semi-indirector an indirect fixture. The lanip bulb C is carried by a lamp socket I)and said lamp socket is incased by a shell E that projects upwardlyabove the top reflector A. The lamp socketD may either be connected to asupporting device 1 on the ceiling of a room and the shell E alsoconnected to said supporting device, as shown in Fig. 1, or said lampsocket and shell can be mounted on apipe, chain or tubular shapedsupporting device 1 that depends from the ceiling, as shown in Fig. 2.

The top reflector A and the bowl B are both carried by a plurality ofdevices 2 which are supported by the shell E, which devices 2 projectdownwardly through a center opening in the top reflector. In thepreferred form of my invention, as herein shown, the devices 2 consistof short pieces of heavy Wire or light-weight rods which are provided attheir upper and lower ends with hooks 2 and .2" that engage the shell Eand the bowl B, respectively, said devices 2 being provided intermediatetheir tance above the edge of the center opening i the top re? alowermost po.

in the top reflector A, and in the preferred form of my invention. asherein shown, the

shell E is provided with openings 3 for receiving the hooks 2 at theupper ends of the deices 2. The shell i is preferzihly provided withmeans for holding the dewhich means vices in 11 vertieal position, mayronsist of an outwardly"projecting flange 4 at the lower end oi, themidi E, which is provided with notches the receive the devices 2, asshown in Fig, i.

In order that different sized lightin may he used without destroying therope relation between the lilznnent of the lighting unit and thereflector A and bowl ll. 1 have providedthe shell 1) with a plural ofsets of o 'ieningrs arranged in dili eri hori ontal planes for receivingthe hooks on the devices 4 thereby enabling the to reflector and thebowl. or dilins'ii he raised and lowered with relzo' lamp socket U thatsupports i'lie.ii;1litiiw unit. in the form of my invention he shown theshell E is provided with a of top openings 3 and a set of bottomopenings 3 that are arranged in a lower horizontal plane. il hen a shorthull) ('l is used, the hooks at the upper ends of the devices 2 areinserted in the. top openings 3, and when a longer bulb is used. saidhooks are inserted in the set of bottom openings 3. The flange 4 at thelower end of the shell E is provided with a separate set of note-hes 5for receiving the sustaining devices 2 when the hooks at the upper endsof said devices are ar ranged in the lower set of openings of the shell,the notches 5 being. a trifle deeper than. the notches so that the willextend approximately parallel to the a E when said devices are emergedMOI}.
